Self-strutting friction anchor for stabilizing pipes and building constructions

Description

The anchor consists of a steel pipe and bottom base plate. The 3-4 mm groove is cut lengthwise the pipe. The pipe is filled with solution of a special expanding substance before installation into a hole. High pressure rises on the pipe walls in the course of the solution hardening and expansion. Under pressure the pipe unfolds round the groove and firm contact forms between the pipe surfaces and hole, then the anchor reaches its operating capacity. Unlike the currently used frictional anchors, the new anchor does not need any special equipment to be installed into a hole and is characterized by the improved technological and power properties.
